Pitch Raise Sequence

[Joe & Penny Goss]

Hi Ron,
It is a matter of just pulling the string to the pitch that the SAT shows
the overpull for and then  going quickly to the next string.
As you are tuning both the first then the second string they will go flater.
And as the third string is tuned to the first and second string the first
and second string will fall further.
